The Lost City of the Indus Civilization refers to the ancient city of Mohenjo-daro, which was one of the largest cities of the Indus Valley Civilization. The Indus Valley Civilization was a Bronze Age civilization that existed in the region of modern-day Pakistan and northwest India from approximately 2600 BCE to 1900 BCE.
Mohenjo-daro was discovered in the 1920s by archaeologists, and it is one of the most well-preserved examples of an Indus Valley Civilization city. The city is believed to have been home to over 40,000 people at its height and was a center of trade and industry.
The city was built with an advanced system of drainage and sanitation, which included public baths and toilets that were connected to a sophisticated underground sewage system. The city also had a complex system of weights and measures, suggesting a highly organized and centralized government.
Despite its advanced civilization, the Indus Valley Civilization remains something of a mystery to historians and archaeologists, as its writing system has not yet been deciphered. The reasons for the decline and eventual disappearance of the Indus Valley Civilization are also still debated by experts, with theories ranging from climate change to invasion by outside forces. Nonetheless, the discovery of Mohenjo-daro and other Indus Valley Civilization sites provides a fascinating window into the ancient history of the region.
